Fiber-metal laminates (FML) composed of alternating layers of unidirectional fibers-reinforced plastic (FRP) laminae and aluminum-alloy sheets offer some superior mechanical properties, compared with either conventional laminates consisting of only, FRP laminae or high-strength monolithic aluminum alloys. The environmental factors can limit the applications of composites by deteriorating the mechanical properties during service. Usually, polymeric matrix absorbs moisture when exposed to humid environments and metals are prone to surface corrosion. on the other hand, FML laminates presents more resistance of moisture when compared with their constituents. Evaluation of shear properties is particularly important in the design of mechanically, fastened parts and components, which are subject to parallel and opposing loads. In this work, the shear behavior was studied for Glare laminates and its constituents in dry and wet conditions.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)UNESP Dept. of Materials and Technology, Guaratinguetá, SPCTA-IAE Materials Division, Säo José dos Campos, SPUNESP Dept. of Materials and Technology, Guaratinguetá, SPFAPESP: 05/54358-7FAPESP: 03/04240-4CNPq: 306053/2006-3
